This is a single-center, randomized controlled clinical trial to compare the effectiveness of vision therapy and prism wearing for the treatment of small-angle acute acquired concomitant esotropia.
Aged 10-40 years (including 10 years and 40 years);
Best-corrected visual acuity no worse than 20/20 for both eyes;
Deviation angle less than 15 prism diopters (including 15 prism diopters);
Organic eye diseases;
Lesions of the brain;
Receiving esotropia therapy(including surgery and prism treatment)
Devation angle reducing more than 10 prism diopters after refractive correction
